Description Mark Salter 2002-04-12 03:44:34 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.2.1) Gecko/20010901

Description of problem:
The ether_ntohost() function causes a segfault. It looks like it is being
miscompiled. Looking at the source, it calls __nss_ethers_lookup(), but when
disassembled in gdb, it is actually calling __nss_passwd_lookup().

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Run "tcpdump -i eth0" or any app calling ether_ntohost().
2.
3.
	

Actual Results:  segfault

Expected Results:  No segfault.

Additional info:

This app demonstrates problem:

main()
{
    unsigned char addr[6] = { 0xff, 0xff, 0xff, 0xff, 0xff, 0xff };
    char name[256];
    ether_ntohost(name, addr);
}
